Climate resilience, also known as carbon resilience, is a key capability for the 21st century. This resilience describes how individuals, businesses and cities prepared to face the challenges of climate change. It is not just about passively knowing about the problems, but about actively implementing solutions – whether it is reducing greenhouse gas emissions (mitigation) or adapting to the consequences of extreme weather such as heat waves and floods. Being climate-smart means having the ability to make informed judgments and take effective decisions regarding the use and management of carbon, both through individual behavioral change and collective action. Today, it is clear that these two directions – preparation and emission reduction – must go hand in hand.

Cities and municipalities: Green infrastructure and resilience

Cities around the world are a double-edged sword in the climate crisis: they contribute significantly to CO₂ emissions (especially through buildings and transport), but they also feel the consequences of warming most intensely, such as storms, droughts and heat waves. That is why they are preparing comprehensive climate plans.

An example is Bratislava, which adopted the Sustainable Energy and Climate Action Plan (SECAP), which aims to reduce emissions by 55 % by 2030 (compared to 2005) and achieve climate neutrality by 2050. Key measures include extensive insulation of buildings, modernization of public lighting to LED technology, development of electromobility, including the construction of 400 new charging stations, and expanding the tram network.

Climate-smart cities also invest massively in green infrastructure, which is a very effective means of combating urban overheating and flooding, according to the European Environment Agency. Trees and plants provide natural shade, cool the air by evaporating water and filter pollutants. Parks and green roofs are able to absorb significant amounts of rainwater, thereby mitigating the risk of flooding. That is why many cities, including Bratislava, are establishing urban climate axes, planting climate-friendly trees in the streets and investing in infiltration and retention facilities to retain water.

Under the Covenant of Mayors programmes, cities are combining mitigation and adaptation efforts. Bratislava has received EEA grants for projects focusing on green roofs, rainwater harvesting and tree planting to cool city districts. Similarly, other Slovak cities (such as Košice) are preparing adaptation plans aimed at increasing resilience to floods and heat waves. These steps protect the most vulnerable residents (children, the elderly) from climate extremes and improve air quality.

Companies: Carbon footprint measurement and ESG

Climate resilience is also key for the business sector today. Companies measure their climate performance, primarily carbon footprint, which quantifies the greenhouse gas emissions produced. Emissions are divided into three categories:

• Scope 1: Direct emissions from own production and vehicle fleet.
• Scope 2: Emissions from purchased energy, such as electricity.
• Scope 3: Indirect emissions, for example from the supply chain and product use.

International standards such as the GHG Protocol or ISO 14064 help companies summarize this data.

The measurement results are reflected in ESG ratings (Environmental, Social, Governance), which assess how effectively a company manages environmental and social risks. A climate-smart company sets ambitious targets, often in line with the Paris Agreement, and investors today demand a clear strategy for reducing emissions and regular climate reporting (for example, according to ESRS or TCFD guidelines).

Measures taken by climate-smart companies include: investments in renewable energy sources, increasing the energy efficiency of production processes, switching to electric vehicles and changing supply practices (e.g. using 100 % of green electricity or sustainable raw materials). For example, the food group Danone has committed to achieving carbon neutrality in its entire supply chain by 2050 and is using the Science Based Targets (SBTi) initiative. Similarly, Heineken Slovensko has set itself carbon neutrality in production by 2030 and in the entire value chain by 2040, with "net-zero" in the sense of the SBTi standard meaning reducing CO₂ to a minimum and offsetting a maximum of 10 % of the remainder.

New research from Harvard Business School confirms that 45% of large US companies in “climate-critical” industries were investing in or developing climate solutions in 2023. These companies see the transition to low-carbon technologies not only as an obligation, but also as a business opportunity.

Individuals: From Behavior to Systemic Change

Finally, climate resilience is essential for every individual. It is important to link reducing one's carbon footprint with being prepared for extreme events.

In the area energy Households can contribute by replacing light bulbs with LEDs, insulating buildings, installing solar panels and efficient appliances. According to WRI, installing renewable energy sources and increasing household energy efficiency are among the most important steps.

IN transportation It is essential to prioritize walking, cycling or public transport over driving. WRI research shows that giving up your car has a huge impact and reduces the emission load by about the same amount as composting for 77 people. It is also important to reduce air travel and replace it with trains or online meetings.

Vo diet and consumption Switching to a more plant-based diet and limiting meat and dairy can significantly reduce personal emissions; a vegan diet currently saves around a tonne of CO₂ per year (about a sixth of the average annual carbon footprint). It is also important to shop locally, reduce food waste and use reusable packaging (e.g. cloth bags).

At the same time, we must prepare for more extreme weather. Individuals can manage heat and storms by planting trees around their homes, installing effective shading (blinds, awnings), and landscaping their gardens to better drain rainwater. In hot weather, it is important to drink plenty of fluids and avoid the intense sun. During torrential rains, it is important to keep drains clear and protect property with flood barriers.

A climate-savvy person cannot remain indifferent. They can engage in community activities (planting trees, community gardens), support environmental organizations, and spread information. Citizens also have the opportunity to push for responsible policies, elect leaders who take the climate seriously, and actively demand climate action at all levels. A combination of small daily steps and engagement in public debate it is the cumulative effect of our climate resilience.

A comprehensive approach – from building green infrastructure in cities, through ESG commitments by companies, to changing the lifestyles of individuals – ensures that climate change does not surprise us, but strengthens us. We become truly climate-smart. JRi
