Assessing Climate Initiatives: From Households to the Paris Agreement (2026)

Let's start with a question

Since the 1990s, countries have signed climate agreements, governments have passed laws, cities have written plans, and millions of people have changed how they live. Yet global emissions reached new record highs in the mid-2020s. Does that mean climate initiatives don't work?

Not exactly. Some initiatives have worked very well; some have worked a little; some were cancelled before they could work; and some were never strong enough. In this lesson you'll learn how to assess an initiative fairly, using criteria and evidence, the way a policy analyst would, and then propose what should happen next.

Note: climate policy changes often. The facts here are current as of the fall of 2026. Always check a current source before you use them.

How to assess effectiveness: criteria

An initiative is effective if it achieves its goals at a reasonable cost, without causing bigger problems. Useful criteria:

1. Emissions impact: how many tonnes of CO₂e does it actually reduce (or how much harm does an adaptation avoid), compared with what would have happened without it?
2. Scale: is the impact large compared with the problem?
3. Cost-effectiveness: what does each tonne reduced cost?
4. Speed and durability: how soon does it work, and is it likely to last, or can it easily be reversed?
5. Fairness: who pays, and who benefits? Does it protect people with lower incomes and communities most affected by climate change?
6. Co-benefits and side effects: cleaner air, jobs, lower bills, or harms?
7. Evidence: is there measured, independently checked evidence, or only promises?

International initiatives

• Kyoto Protocol (1997): set binding targets for developed countries. Canada ratified it but did not meet its target, and withdrew in 2011. Lesson: binding targets without a plan to meet them don't work.
• Paris Agreement (2015): nearly every country agreed to hold warming well below 2 °C and pursue 1.5 °C. Each country sets its own target (its NDC) and must strengthen it every five years. At COP28 in Dubai (2023), countries agreed for the first time on the need to transition away from fossil fuels in energy systems. COP30 was held in Belém, Brazil, in November 2025.
• The United States, the second-largest emitter, withdrew from the Paris Agreement again; the withdrawal took effect in January 2026.
• Assessment: recent UN assessments estimate that current policies put the world on track for close to 3 °C of warming by 2100, better than the 4 °C or more projected before Paris, but far above its goals. Paris has made progress, but countries' actions are not yet strong enough.
• Montreal Protocol (1987): the most successful environmental treaty so far (Lesson 12). It shows what effective international action can look like.

National initiatives: Canada in 2026

• Targets: the Canadian Net-Zero Emissions Accountability Act (2021) requires net-zero emissions by 2050. Canada's targets are 40 to 45% below 2005 levels by 2030 and 45 to 50% below 2005 by 2035.
• Where we are: Environment and Climate Change Canada's 2026 inventory reported 685 Mt CO₂e in 2024, about 10% below 2005 (763 Mt), and about 17 tonnes per person, down from 24 tonnes in 2005. Canada produces about 1.4% of global emissions but has one of the highest emissions per person in the world.
• Carbon pricing: the federal consumer fuel charge (the carbon price on gasoline and home heating fuels) was set to zero on April 1, 2025. Industrial carbon pricing, which applies to large emitters such as oil and gas facilities, steel and cement plants, continues. In 2025 and 2026, the federal government and Alberta signed agreements that centre on strengthening Alberta's industrial carbon price, cutting methane from oil and gas by 75% below 2014 levels by 2035, and a large carbon capture and storage project, alongside plans for a new oil pipeline. The federal government also said its proposed cap on oil and gas emissions would no longer be needed if these measures work.
• Other policies: a commitment to phase out coal-fired electricity by 2030; methane regulations; programs for clean electricity and home retrofits. The federal electric vehicle sales mandate was paused in 2025 and the government moved to repeal it in 2026.
• Assessment: in late 2025, Canada's Parliamentary Budget Officer projected that 2030 emissions would be only about 31 to 34% below 2005, short of the 40 to 45% target. Emissions have fallen, especially from electricity, but not nearly fast enough to meet the targets. Debate continues over which policies are most effective and fair.

Regional (provincial) and municipal initiatives

• Ontario's coal phase-out: in the early 2000s, coal produced about a quarter of Ontario's electricity. The province phased it out, and the last coal-fired plant stopped burning coal in 2014. Emissions from Ontario's electricity sector fell sharply, and smog advisories became much rarer. This is widely considered one of the most effective climate actions in Canada. Today Ontario's electricity comes mostly from nuclear and hydroelectric power, with growing use of natural gas, wind and solar as demand grows.
• Ontario's cap-and-trade program started in 2017 and was cancelled in 2018; the province now uses its own industrial emissions performance standards. Quebec has run a cap-and-trade system since 2013, linked with California's since 2014.
• British Columbia introduced North America's first broad carbon tax in 2008; like the federal consumer charge, its consumer carbon tax ended on April 1, 2025.
• Municipal: many cities have climate plans. Toronto's TransformTO aims for net-zero community emissions by 2040; the Toronto Green Standard sets energy performance requirements for new buildings. Cities also build transit and bike lanes, plant trees, and prepare for heat and floods (adaptation).
• Indigenous-led initiatives: First Nations-led projects such as Wataynikaneyap Power, which is connecting remote First Nations in northwestern Ontario to the power grid and reducing reliance on diesel, combine emissions cuts with community benefits and self-determination.

Individual initiatives

Individual actions add up, especially in a country with high emissions per person, and they influence others. Actions with the biggest impact are usually about transportation (fewer car trips, transit, cycling, an efficient or electric vehicle, fewer flights), home energy (insulation, a heat pump, a lower thermostat), and food (wasting less, eating more plant-based meals). Just as important are civic actions: voting, speaking to elected officials, and joining community projects.

But individual actions alone can't reach net zero. Many choices depend on systems: you can't take transit that doesn't exist, or buy clean electricity if the grid isn't clean. Effective climate action needs individuals and governments and businesses.
