It’s likely that there will be no successful green transition without an element of carbon capture, storage and re-use. The oil industry has been burying CO2 underground since the 1970s, so the infrastructure and technology is already available, but removing CO2 from the air at scale is new, and the companies doing it are small. We head to an experimental ‘direct air capture’ plant in Canada to hear how they are making fuel out of air, and explore what changes will be required to ensure that their industry becomes a significant one in the years to come. But if we think that a technology fix is out there, might we limit other efforts?

Cities emit around three-quarters of the world’s greenhouse gas emissions, according to the United Nations, and over half of the world’s population now live in one. Many have set ambitious targets to slash and offset their emissions, in the hope of neutralising their impact on the environment and slowing climate change.

Scientists agree that cutting carbon emissions as soon as possible is key to tackling global warming. But as emissions continue to rise, some are now calling for more research into measures that could be used alongside decarbonisation, including – controversially – what’s known as ‘solar geoengineering’ technologies.

More than two thirds of our planet is covered by the oceans, but there’s still much to be uncovered about the role that these watery worlds play in climate change.

South Korea’s economic development has been the envy of many nations: from war, famine and poverty to one of the richest countries on Earth, all within just a couple of generations. In 1955, gross domestic product was just $64 per capita. Last year, it was $31,000. But this growth was turbocharged by fossil fuels, and has come at a high environmental price. Seventy percent of the power generated in the country comes from fossil fuels and, compared to many rich nations, its commitment to renewables is small. Is South Korea a hero of economic growth or a climate villain? And should developing nations still look to the country as a model to follow?

Indigenous people represent only about six percent of the world’s population, but they inhabit around a quarter of the world’s land surface. And they share these regions with a hugely disproportionate array of plant and animal life. According to the UN and the World Bank, about 80 percent of our planet’s biodiversity is on land where indigenous people live.

Global climate policy has however been slow to recognise that indigenous knowledge - built up over centuries - is worth listening to. This is despite the fact that sometimes in very remote areas, where scientific and meteorological data is lacking, this knowledge may be all there is. Indigenous knowledge can provide valuable insight into what adaptations have worked in the past, and so provide an important guide to the future.

What are the barriers to bringing indigenous knowledge out from the margins of climate research and policy, and can they be overcome?

From fruit rotting in fields, to retailers turning down funny shaped vegetables, and consumers scraping leftovers into the bin, food waste is everywhere. It’s estimated that around a third of all our food ends up not being eaten. If we could sort this, total greenhouse gas emissions would reduce by around eight percent. To put that in context, the only countries that are responsible for emissions of that size are China and the US.

So, what can be done? Graihagh Jackson and Jordan Dunbar discuss fixes - big and small - and hear from a farmer in Morocco turning apples that would otherwise rot into vinegar. The first thing that needs to happen for change to start is for governments to properly count the climate cost of food waste. And that, it seems, is a long way off.

More companies are rolling out carbon dioxide emission labels on products to help us make greener choices. Unilever, the global consumer goods giant, recently announced it is committing to put carbon footprint information on 70,000 products, while multi-national companies Oatly and Quorn have already started adding labels like this to their packaging.

President Biden has invited the world’s major polluters to a summit on Earth Day (April 22nd). It may be the biggest climate summit ever organised by an American leader. On the campaign trail last year, Mr Biden said climate change was his “number one issue.” Now, the pressure is on for him to make a big announcement.

But while the US has rejoined the Paris Climate Agreement, it has no official plan to hit the Paris targets. Frantic work is underway in the US to come up with something that satisfies the President’s lofty campaign rhetoric but can actually get through America’s polarised, gridlocked political system.

Ahead of the summit, The Climate Question is reaching out to climate diplomats and experts from China, Bangladesh, the EU and beyond, to hear what the world expects from the US on climate change.

Cities, money, roads, beef burgers and telephones, in fact pretty much all of human civilisation as we know it, would probably not exist were it not for one simple invention. The plough.
