Climate footprint: how your habits affect the climate

Your climate footprint, more often called your carbon footprint, measures the impact your everyday habits have on the climate. According to the IPCC, limiting warming to 1.5 °C needs rapid and deep cuts in global greenhouse gas emissions this decade. Every reduction counts, and the first step is knowing where your own emissions come from.
