Nature and biodiversity 

At Holcim we are committed to delivering a nature-positive future.

With the launch of our nature strategy in September 2021, Holcim is among the 1% of the 500 largest global companies with science-driven biodiversity targets, and the first in our sector with a freshwater replenishment commitment.

Our nature strategy sets out measurable 2030 targets to restore and preserve biodiversity and water, while at the same time bringing more nature into cities.

Our focus areas:


Our positive impact on biodiversity is based on transformative rehabilitation plans and measured by a science-based methodology developed in partnership with the International Union for Conservation of Nature (IUCN).


Preserving water across our business, we aim to replenish freshwater in water-risk areas while lowering water intensity across all our product lines.


Our stories 

Environmental Sustainability

Kenya’s coastal forests are of critical importance to the country as they support communities by providing much needed ecosystems goods and services including fuelwood, herbs, air purification, water, ecotourism, sports and recreation.

These coastal forests are highly fragmented and under immense threat due to population pressure leading to unsustainable practices like charcoal burning, pollution among others.

In response to the above, Bamburi Cement continues to grow and manage forest plantations and ecosystems in both rehabilitated quarries and reserve lands (which occupy over 700 hectares) for sustainable utilization, protection and conservation in support of environmental sustainability as a critical component in addressing livelihood concerns for socio-economic development.

We continue to spearhead an urgent culture of tree growing and forest protection among Kenyan coastal communities to enable the conservation of globally threatened indigenous varieties of flora and fauna for ecosystems goods and services and sustainable livelihoods.


Biodiversity in our rehabilitated quarries

Sustainable Development Goal (SDG) 15 calls for all to protect, restore and promote the sustainable use of terrestrial ecosystems, sustainably manage forests, combat desertification, halt and reverse land degradation and halt biodiversity loss. In line with this call, LES has established world class ecosystems through the restoration of Bamburi Cement coral limestone quarries.

From onset of rehabilitation in 1971, over 452 species of trees, shrubs and lianas have been introduced into the rehabilitated quarries. Over 195 of these species are listed on the International Union for Conservation of Nature (IUCN) Red List including those designated as Critically Endangered, Endangered, Vulnerable or Near Threatened.

Many of the indigenous species are now reproducing in the restored ecosystems and forming populations that positively impact on ecosystems services. Food plants as well as flowering plants are introduced to attract and sustain the rich biodiversity, including butterflies and birds. More than 292 species of birds have been recorded in the emergent ecosystems.

Eleven (11) of the bird species are listed as either Endangered, Vulnerable or Near Threatened and some are seasonal or occasional visitors to the sites. To date, 35 mammal species have been recorded, some of which are listed as Vulnerable or Near Threatened on the IUCN Red List and 14-amphibian species. In addition, over 112 species of butterflies and 18 species of dragonflies reside in the ecosystems.


Wildlife integration in restoration

Bamburi’s rehabilitation program has created a functional ecosystem over the years through wildlife integration in the rehabilitation of limestone quarries. Animals, many of them larger mammals, were introduced as orphans or rescued, while others were brought in to occupy specific niches in the ecosystem.

Animal species such as monkeys, bush-babies and antelopes, act as seed dispersers, while butterflies and other insects, bats, bush-babies and others act as pollinators. Diverse insects, millipedes and other arthropods and fungi act as decomposers in the ecosystem, turning the former quarry into a functional ecosystem.

Reptiles and other predators were introduce to regulate populations of other organisms. Bamburi’s rehabilitated quarries are a well-documented success story and act as a showcase for the Kenya and its commitment to environmental conservation and management.


Ecotourism and environmental education

Our environmental education programme promotes continuous learning at our sites in support and fulfilment of Sustainable Development Goals 4, which calls for the provision of inclusive and equitable quality education and promotion of lifelong learning opportunities for all. 

We have built a vibrant interactive environmental conservation education that is based on Mining and Environmental Management, and material transformation of resource from mining, through rehabilitation, ecosystems management and biodiversity.

Our education guides and technical staff are on hand to receive, interact and provide educational tours to over 170,000 visitors annually at Bamburi Haller Park and Bamburi Forest Trails.

These experiential tours allow individuals (students included) to explore environmental issues in-depth.
