Sustainability is everywhere in marketing, policy speeches and corporate reports, yet public understanding still lags behind the rhetoric. A global survey on sustainability and the UN Sustainable Development Goals found that while 98 percent of all respondents say they are aware of the concept of sustainability, only about half say they know the SDGs at all.
That gap matters. If people do not understand the vocabulary, they cannot tell the difference between serious action and spin, or hold leaders accountable. Educating people on the fundamentals is not a “nice to have.” It is a precondition for credible climate action, sound investment decisions and basic climate justice.
Below are ten terms that shape global debates on climate and development. There is also the possibility that if the average citizen truly understood these, the politics of sustainability would look very different.
1. Sustainable Development
The modern sustainability agenda is anchored in one sentence. In 1987, the UN’s Brundtland Commission defined sustainable development as “development that meets the needs of the present without compromising the ability of future generations to meet their own needs.”
That definition is not just environmental. It explicitly balances three pillars: economic prosperity, social equity and environmental protection. Sustainable development is the foundation for the 17 SDGs, which range from ending poverty and hunger to climate action and strong institutions.
Yet SDG awareness remains uneven. According to GlobeScan’s 2023 survey across 31 countries, only about 50 percent of people say they have heard at least “some” information about the SDGs, up from 38 percent in 2017. Bridging that literacy gap is the first step toward meaningful participation in sustainability decisions.
2. Net Zero
Net zero is where global warming stops. The UN’s Net Zero Coalition explains that net zero means cutting greenhouse gas emissions to a small amount of residual emissions that can be absorbed and durably stored by natural or technological sinks so that the overall balance is zero.
According to the IPCC, in modelled pathways that limit warming to 1.5 degrees Celsius with little or no overshoot, global net-zero CO₂ emissions are reached in the early 2050s.This is why so many countries and companies are setting “net zero by 2050” targets.
What net zero does not mean is “business as usual plus cheap offsets.” Every credible pathway prioritizes deep absolute emission cuts first. Offsets, carbon credits and removals come last, and must be high quality and transparently reported.
3. Scope 1, 2 and 3 Emissions
When companies talk about their carbon footprint, they are usually using the Greenhouse Gas Protocol’s framework:
- Scope 1: direct emissions from sources the company owns or controls, such as fuel burned in boilers or company vehicles.
- Scope 2: indirect emissions from purchased electricity, steam, heating or cooling.
- Scope 3: all other indirect emissions up and down the value chain, from suppliers to product use and disposal.
According to Carbon Disclosure Project global supply chain analysis, value chain emissions are on average around 11 times higher than a company’s direct operational emissions and can account for more than 70 percent of its total footprint.
If a company talks about “net zero” but excludes Scope 3, it is ignoring the majority of its climate impact. Educated consumers, employees and investors should be asking very specifically which scopes are included.
4. Carbon Footprint
A carbon footprint is the total greenhouse gas emissions caused directly and indirectly by an individual, organization, product or event, usually expressed in tons of CO₂ equivalent. The figure includes fossil fuel use, industrial processes, agriculture and more.
According to Our World in Data, global CO₂ emissions have stayed just below five tons per person for over a decade, but with stark inequality. Per capita emissions in many high-income countries are several times higher than those in low-income countries.
Carbon foot prints turn abstract climate targets into something concrete. It lets households see the impact of flying versus taking a train, or companies compare the lifecycle emissions of different products using robust accounting rather than guesswork.
5. Climate Mitigation
Climate mitigation is about preventing climate change from getting worse. The UNFCCC defines climate neutrality as reducing emissions so that human activities have no net effect on the climate system. Mitigation measures include decarbonizing power generation, improving energy efficiency, protecting and restoring forests and changing industrial and agricultural practices.
Despite progress in renewables, the world is not yet on track. According to recent analysis reported by the Financial Times, global CO₂ emissions from fossil fuels reached about 37.4 billion tons in 2024, a record high, while the world remains on a trajectory of roughly 2.7 degrees of warming. Mitigation literacy helps people make sense of this and what matters is whether global emissions fall steeply this decade.
6. Climate Adaptation
Even with aggressive mitigation, climate impacts are already locked in. Climate adaptation means adjusting human and natural systems to actual or expected climate impacts in order to reduce harm and seize any opportunities.
Adaptation in practice looks like elevating homes in flood-prone areas, redesigning drainage systems in cities, developing drought-tolerant crops or reinforcing hospitals against hurricanes. There is high confidence that climate change is intensifying heavy rainfall associated with tropical cyclones, which raises the stakes for coastal and island communities. This was evident in the recent category 5 hurricane Melissa which devasted parts of Jamaica. For vulnerable regions, adaptation is not optional. It is survival and educated citizens can push for adaptation funding to match the scale of the risk instead of being treated as an afterthought.
7. Circular Economy
A circular economy is a system where materials never become waste and nature is regenerated. The Ellen MacArthur Foundation explains that circularity keeps products and materials in circulation through maintenance, reuse, refurbishment, remanufacture, recycling and composting and aims to decouple economic activity from the consumption of finite resources.
This is fundamentally different from the traditional “take–make–waste” linear model. In a circular model, a smartphone might be designed for easy repair and component reuse rather than one-way disposal. A fashion brand might use durable fibers, offer repair services and run a resale platform rather than relying solely on fast, disposable clothing. Circular economy literacy allows consumers and policymakers to see beyond “recycling” as a cure-all and instead focus on redesigning products and systems to prevent waste at the source.
8. Greenwashing
Greenwashing is the practice of making products, services or strategies appear more environmentally friendly than they really are. It thrives on public confusion and weak oversight.
According to an investigation summarized by the European Commission, national authorities had reason to believe that in 42 percent of cases, online green claims were exaggerated, false or deceptive and could constitute unfair commercial practices.
With three quarters of products in some EU markets now carrying some kind of environmental claim or label, according to analysis cited by SGS, the risk of consumers being misled is real. A public that understands terms like net zero, Scope 3 and circular economy is much harder to fool with vague labels like “eco-friendly,” unsupported offsets or selective disclosure.
9. Blue Economy
The blue economy is about harnessing the economic potential of oceans and coasts without destroying the ecosystems that sustain them. The World Bank defines a blue economy approach as the sustainable use of ocean resources for economic growth, improved livelihoods and jobs while preserving the health of ocean ecosystems.
According to a World Bank assessment, estimates of the ocean’s contribution to the world economy range from 1.5 to 3 trillion dollars a year, roughly 3 to 5 percent of global economic activity. The assessment also states that Caribbean marine resources contribute significantly to the region’s economy. In 2012, activities taking place in Caribbean waters generated an estimated US$407 billion, even though the area represents only about 1 percent of the world’s ocean space. Most of this value comes from market-driven sectors such as shipping, tourism and offshore oil and gas, since many ecosystem services are not easily quantified in monetary terms.
For coastal and island states, including Caribbean countries, the blue economy is not an abstract concept. It covers fisheries, tourism, ports, shipping, offshore renewable energy and coastal protection. Educated citizens can ask whether proposed “blue” investments genuinely restore mangroves, coral reefs and fish stocks or simply rebrand extractive activities with new language.
10. Energy Justice and Climate Justice
Energy justice is about who benefits from and who is harmed by energy systems. It asks whether communities have access to affordable, clean and reliable energy and whether the burdens of pollution and transition are fairly shared.
In the United States, an EPA-funded study found that people of color breathe more fine particulate air pollution (PM₂.₅) on average than white residents, across income levels and regions due to their exposure. That is energy injustice in everyday life.
Climate justice zooms out to the global level. Small Island Developing States account for less than 1 percent of global greenhouse gas emissions, yet they are on the frontlines of sea level rise and stronger storms. The Caribbean region as a whole contributes around 0.1 percent of global emissions, according to UN analysis, yet faces some of the worst climate risks.
Hurricane Melissa made this painfully tangible. According to an attribution study by World Weather Attribution reported by the Associated Press, human-driven climate change increased Melissa’s maximum wind speeds by about 7 percent and rainfall near its center by 16 percent, and made a storm like Melissa roughly six times more likely in today’s warmer climate. The storm devastated parts of Jamaica and other Caribbean nations, destroying homes, critical infrastructure and livelihoods.
When a country like Jamaica, with a small share of global emissions, absorbs repeated multi-billion-dollar hurricane losses while larger emitters continue to burn fossil fuels, the conversation is not only about adaptation or mitigation. It is about justice, accountability and finance. To support the island’s recovery efforts, visit supportjamaica.gov.jm.
Why Literacy On These Terms Matters in Sustainability
Globally, awareness of the idea of sustainability is high, but detailed knowledge of frameworks like the SDGs sits at around 50 percent and understanding of technical terms such as Scope 3 or circular economy is much lower.
Closing that gap changes everything. A citizen who understands net zero will ask how fast emissions are actually falling. A customer who understands Scope 3 will question a company that reports only operational emissions. A voter who understands climate justice will recognise why Caribbean states and other small islands demand stronger global action and fairer finance.
Sustainability is a shared language for negotiating how we live on a hotter, more fragile planet. Teaching these ten terms with real data and honest examples is one of the fastest ways to turn passive concern into informed pressure for change.
